Abstract
In this paper, we propose a robustness enhanced beamformer which does not involve any additional constraint on weight vector beside the distortionless response constraint. The proposed algorithm enhances its robustness against steering vector error by incorporating a term which aims to minimize the cross-correlation between the real and the imaginary parts of the desired signal in the objective function. Extensions of the proposed algorithm to l 1-norm minimization and incorporation of robust constraint are also addressed. Computer simulations verify validity and advantage of the proposed algorithm.
